5. Maintenance
Regular maintenance will extend the lifespan and preserve the appearance of your Domi Metal Garage Shed.
5.1 Cleaning:
- Clean the exterior panels periodically with mild soap and water. Avoid abrasive cleaners or harsh chemicals that could damage the powder coating.
- Rinse thoroughly with clean water.
- Clear any debris, leaves, or snow from the roof to prevent excessive load and ensure proper drainage.
5.2 Inspection:
- Periodically inspect all bolts, screws, and fasteners to ensure they are tight. Tighten any loose connections.
- Check for any signs of rust, especially in areas where the coating might be scratched or damaged. Touch up with rust-inhibiting paint if necessary.
- Inspect door hinges and latches for smooth operation. Lubricate with a silicone-based spray if they become stiff.
- Ensure the shed remains securely anchored to the ground.

6. Troubleshooting
This section addresses common issues you might encounter with your metal garage shed.
6.1 Water Leaks:
- Check Panel Seams: Ensure all roof and wall panels are correctly overlapped and fastened according to the assembly instructions.
- Inspect Fasteners: Verify that all screws and bolts are tight and that no washers are missing or damaged.
- Sealant Application: If leaks persist, consider applying an outdoor-grade silicone sealant to external seams, especially around the roof and corners.
6.2 Door Sticking or Misalignment:
- Lubrication: Apply a silicone-based lubricant to door hinges and tracks to ensure smooth operation.
- Check Levelness: Ensure the shed's base is perfectly level. An uneven base can cause door frames to twist and doors to stick. Adjust the base if necessary.
- Inspect for Obstructions: Clear any debris or dirt from the door tracks or around the door edges.
6.3 Instability in Wind:
- Verify Anchoring: Double-check that the shed is securely anchored to the ground using appropriate hardware. Ensure anchors are fully engaged and tight.
- Foundation Integrity: Confirm that the foundation (concrete slab, gravel base) is stable and not eroding.
